!CAUTION
►Switch off power supply before installing or connecting the device. Failure to observe this
may result in destruction of parts of the electronics.
►When installing Ex-approved devices in a hazardous area, please take special note of the
instructions and connection schematics in the respective Ex documentation added to these
Operating Instructions. The local Endress+Hauser representative is available for assistance if
required.
►Do not occupy the display connection. An incorrect connection can destroy the electronics.
For wiring a mounted head transmitter, proceed as follows:
1. Open the cable gland and the housing cover on the terminal head or the field housing.
2. Feed the cables through the opening in the cable gland.
3. Connect the cables as shown in (® ä 11). If the head transmitter is fitted with spring
terminals, pay particular attention to the information in the "Connecting to spring
terminals" section .
4. Retighten the cable gland and close the housing cover.
In order to avoid connection errors always take note of the hints given in the section connection
check!

5.2 Connecting the sensor cables
NOTICE
When connecting 2 sensors, ensure that there is no galvanic connection between the
sensors (e.g. caused by sensor elements that are not isolated from the thermowell).
The resulting equalizing currents distort the measurement considerably.
►The sensors must remain galvanically isolated from one another by connecting each sensor
separately to a transmitter. The transmitter provides sufficient galvanic isolation (> 2 kV AC)
between the input and output.

observe this may result in destruction of parts of the electronics.
Cable specification
•A normal device cable suffices if only the analog signal is used.
• A shielded cable is recommended for HART® communication. Take the plant grounding
concept into consideration.
Please also observe the general procedure on (® ä 10).

• The terminals for connecting the signal cable (1+ and 2-) are protected against reverse
polarity.
•Conductor cross-section:
– Max. 2.5 mm2 for screw terminals
– Max. 1.5 mm2 for spring terminals
5.4 Shielding and grounding
Optimum electromagnetic compatibility (EMC) can only be guaranteed if the system components
and, in particular, the lines are shielded and the shield forms as complete a cover as possible.
HART®-communication allows three different types of shielding:
• Shielding at both ends.
• Shielding at one end on the feed side with capacitance connection to the field device.
• Shielding at one end on the feed side.
With regard to EMC, the best results are achieved in most cases with one-sided shielding on the
feed side (no capacitance connection to the field device). Operation in the event of disturbance
variables as per NAMUR NE21 is thus guaranteed.

NOTICE
If the shielding of the cable is grounded at more than one point in systems without
potential matching, power supply frequency equalizing currents can occur that damage
the signal cable or have a serious effect on signal transmission.
►In such cases the shielding of the signal cable is to be grounded on only one side, i.e. it must
not be connected to the ground terminal of the housing (terminal head, field housing). The
shield that is not connected should be insulated!

3: DIP switch (WRITE LOCK = write protection; DISPL. 180° =
switch, turn the display monitor 180°)
Procedure for setting the DIP switch:
1. Open the cover of the terminal head or field housing.
2. Remove the attached display from the head transmitter.

Operating options iTEMP® TMT82

3. Configure the DIP switch on the rear of the display accordingly. In general: switch to ON
= function enabled, switch to OFF = function disabled.
4. Fit the display onto the head transmitter in the correct position. The head transmitter
accepts the settings within one second.
5. Secure the cover back onto the terminal head or field housing.
Switching write protection on/off
Write protection is switched on and off via a DIP switch on the rear of the optional attachable
display. When write protection is active, parameters cannot be modified. This is shown on the
display as a key symbol when a hardware lock is activated ("WRITE LOCK" to "ON").Write
protection prevents any write access to the parameters.
Turning the display
The display can be rotated 180° using the "DISPL. 180°" DIP switch. The setting is retained
when the display is removed.
6.2 Configuration of the head transmitter via HART® protocol
The configuration of the head transmitter and measured value display is performed via HART®
protocol or CDI (= Endress+Hauser Common Data Interface). Special configuration systems are
available for this purpose:
Configuration software
FieldCare SIMATIC PDM
(Siemens)
AMS Device Manager
(Emerson Process Management)
Field Communicator 375, 475
(Emerson Process Management)
NOTICE
Before accessing the device with the Commubox FXA291 via the CDI (Endress+Hauser
Common Data Interface) interface, disconnect the transmitter from the power supply,
terminals (1+) and (2-).
►Failure to comply with this instruction can result in damage to parts of the electronics.
A detailed step-by-step description of configuring device-specific parameters is given in the
Operating Instructions on the CD-ROM provided.

Endress+Hauser 19
7 Commissioning
7.1 Function check
Before commissioning the measuring point make sure that all final checks have been carried out:
•Checklist “Post-installation check”, (® ä 10)
•Checklist “Post-connection check”, (® ä 15)
7.2 Switching on the head transmitter
Once the final checks have been successfully completed, it is time to switch on the supply voltage.
The head transmitter performs a number of internal test functions after power-up. As this
procedure progresses, the following sequence of messages appears on the display:
Step Display
1 "Display" text and firmware version of the display
2 Firm logo
3 Device name with firmware and hardware versions
4 Information on the sensor configuration (sensor element and type of connection)
5 Set measuring range
6a Current measured value or
6b Current status message
If the switch-on procedure is not successful, the relevant diagnostics event, depending on the cause, is
displayed. A detailed list of diagnostic events and the corresponding troubleshooting instructions can be
found in the Operating Instructions on the CD-ROM.
The device is operational after approx. 8 seconds, and the plug-in display after approx. 12 seconds
in normal operating mode! Normal measuring mode commences as soon as the switch-on
procedure is completed. Measured values and status values appear on the display.
7.3 Enabling configuration
If the device is locked and the parameter settings cannot be changed, it must first be enabled via
the hardware lock. The device is locked using the hardware if the keyhole symbol appears in the
header of the measured value display. To unlock the device, switch the write protection switch
on the back of the display to the "OFF" position (® ä 17).
